NewBeeDrone HummingBird V3.1 RaceSpec 1S 12A AIO (FC+ESC+RX+VTX)

HummingBird V3.1 AIO is a board combining a flight controller, ESCs, RC receiver, and analog video transmitter in one. The board supports 1S battery power and is designed for small Tinywhoops and Toothpicks.

The board's base is a flight controller with an F411 processor and a BMI270 gyro. The ESCs use Bluejay firmware and can handle current up to 12A. The integrated SPI ELRS receiver uses the 2.4GHz band. The antenna is connected via an MHF3 connector. The Video Transmitter transmits at a maximum power of 25mW. The antenna is connected to the video transmitter via a u.FL connector. The RaceSpec variant tries to keep the weight to a minimum. The board does not have LEDs or connectors for connecting motors without soldering. The board uses the thicker A30 connector.
